The phrase "at low extent" is not correct and not commonly used in written English.
It seems to be an attempt to describe a minimal degree or level of something, but it is not a standard expression.
Example: "The changes in temperature were at low extent, barely affecting the overall climate."
Alternatives: "to a small degree" or "to a limited extent."
There is a high-rate first-order autoxidation regime below 150 °C and second-order autoxidation regime at low extent of oxidation at temperatures above 150 °C (Babu and Cormack 1983).
AnxA1 was expressed at low extent in livers of naïve mice, whereas both mRNA and protein content increased in a time-dependent manner in livers of animals with NASH induced by feeding the MCD diet (Fig. 1).
It is useful to emphasize that, although the ATP concentration is changing in this experimental design, the ratio of γ-O3-ATP/γ-O4-ATP is a valid indicator of PIX at low extent of ATP hydrolysis, unless there were a kinetic isotope effect favoring hydrolysis of the γ-O3-ATP.
It is important to note that acetylation of PEI has been found to increase its ability deliver plasmid DNA [ 22, 23] in contrast to the present study in which amine acetylation of PAMAM either did not affect (at low extents) or decreased (at high extents) the delivery of siRNA.
The annealing did not affect the topography and the roughness of the coatings, while improved the hardness of the films un-doped and doped at low-extent.
These results indicated that although PLA itself was not an effective gene carrier, however, when combined with CS, it probably helped provide the positive charge to the polyplexes at pH 7.4 where CS alone could be protonated at the low extent.
However, TEM shows the existence of intercalated clay regions, but at a very low extent.
The analysis showed that positively selected cells were hardly detectable at 5 and only to a low extent at 30 minutes after transfer, while negatively selected cells were clearly detectable at both time points with a decreasing concentration probably reflecting the normal cellular turnover (Fig. 4A).
Thirty-one sets of kinetic data collected at 220 °C with a low extent of deactivation were used for kinetic parameter regression.
The R1180P mutant is detected, albeit to a low extent, at the plasma membrane and is rapidly solubilized and secreted into the culture medium.
When general chemicals as a separate group are taken as substrates, FMO and AKR enzymes participate at equally low extents (∼3%, Figure 2A).
